ECOLOGY OF GROUND-DWELLING CARABID BEETLES (COLEOPTERA: CARABIDAE) IN THE PERUVIAN ANDES BY SARAH A. MAVEETY A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADUATE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology December 2013 Winston-Salem, North Carolina Approved By: Robert A. Browne, Ph.D., Advisor Terry L. Erwin, Ph.D., Chair T. Michael Anderson, Ph.D. William E. Conner, Ph.D. Miles R. Silman, Ph.D. ACKNOWLEDGMENTS First, I would like to thank to my advisor, Dr. Robert Browne, who has played a pivotal role in my time at Wake Forest University, encouraging and supporting my research endeavors since my sophomore year as a biology undergraduate. I would also like to thank Biology Department committee members, Dr. Miles Silman, Dr. Bill Conner, Dr. Michael Anderson. The dissertation research would not have taken place in Peru had it not been for Dr. Silman’s long standing research presence there, and I am grateful for his connection. Dr. Conner was my first professor in biology ten years ago, and he has given invaluable insight as the first reader of the dissertation. Dr. Anderson provided instrumental ecological perspective in both my academic career and dissertation. A special thanks to my outside committee member, Dr. Terry Erwin, Curator of Coleoptera at the Smithsonian National Museum of Natural History, and Neotropical carabid beetle expert. He has dedicated his time and expertise so that my specimens were identified correctly and I made all the appropriate connections to colleagues in both Peru and the U.S. The field portion of this project was supported by a Fulbright Grant to conduct research in Peru, and I thank the onsite staff of the Comisión de Fulbright in Lima, Peru. I am also grateful to colleagues at the Museo de Historia Natural Universidad Nacional Mayor de San Marcos, Dr. Gerardo Lamas, Juan Grados, and Luis Figueroa, for help in obtaining permits for beetle collection and exportation. For assistance with field logistics I’d like to thank: Asocación para la Conservación de la Cuenca Amazonica (ACCA); Daniel Blanco at PeruVerde; ProNaturaleza; students and professors at Universidad Nacional San Antonio del Abad Cusco and the Museo de Historia Natural, especially my ii field assistants Jessica Ttito Quispe and Carla Chaparro Zamalloa; and Hubert Jaquehua Callo, No lo hubiera logrado sin ti. Finally, I want to thank former Browne lab graduate students Carmen Chavez and Doug Bruce for sharing Appalachian ground beetle data, and to all the undergraduates who helped in data collection and helped me to meticulously measure individual body lengths. Thank you to my all friends at Wake Forest University, but especially to Rachel Hillyer for her friendship and for help studying for preliminary exams, and to Katie Riley, for going through the ups and downs of graduate school as both a best friend and colleague. I thank my best friends from home, Jessica Young, Tracey Young, and Kasee Metcalf for always being there for me. But above all I am most grateful for the constant loving support of my family who have always encouraged me to do my best. iii TABLE OF CONTENTS ACKNOWLEDGMENTS
